Okay, I've isolated a problem with raid1/md under 2.5.27...
Scenario:
/dev/hda2 and /dev/hdb2 are unused partitions.
/etc/raidtab: raiddev /dev/md0 raid-level 1 nr-raid-disks 2 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device /dev/hda2 raid-disk 0 device /dev/hdb2 raid-disk 1
mkraid /dev/md0
Fails with a kernel panic. A bit of searching finds that this chunk of code (md.c, about line 850): rdev = list_entry(&mddev->disks.next, mdk_rdev_t, same_set); sb = rdev->sb;
memset(sb, 0, sizeof(*sb));
Is failing. sb is == 1 !!
Anyone got any ideas?
